摘要
Poly(ethylene glycol)-modified beta-diketone macroligand is developed to sensitize europium(III) ions in water. High luminescence intensity characteristic of Eu3+ was achieved due to spontaneous formation of micelle-like structure in which the hydrophobic core prevents luminescence-quenching by water molecules. The pH is found to induce a quantitative ratio change in two fluorescence bands from both ligand and Eu3+.
